MF 165 PTO has lost most of it power.

Hi,

I recently had a repair / adjustment done to my dual stage PTO / Clutch on my MF 165 (hope that the right term)

Everything worked fine for about 20 hours, I was told the bolts was loose.

I was just outside trying to adjust the 3 adjusters under the inspection plate, but it seems no matter how much I loosen the bolt shown on the left (towards the rear of the tractor) it just stays in place. There seems there is no way to insert a feeler gauge from what I can tell.

Never done this before, searched on the internet for hours, but alas I can't seem to get the left bolt away from the little "metal block" for lack of a better term..

I know this is noobish question, but I really have tried this repair and I simply must be missing something.

If someone could help me out, that would be great, thing hardly cuts in 1 gear low now:( and I got a field to cut.

Not sure if I need to jam the feeler gauge in there or if the bolt head should move away from the block of metal (little 1" or so square piece).

Anyhow lemme know what you think and thanks.

I also noticed the square block is a good 1/8" away from the backing of the plate(guess that's what it's called)

unlike in this post where it's shown flush.

Thanks for your time,

Hi,
First of all is there any sign of oil present around the clutch unit in the way of an oil film covering it? If the unit is dry then it is unlikely that it is oil contamination. What I would suspect is that the lining on one side of the PTO plate has broken, come loose and got sandwiched in a 'good' part of the plate.
Using a flashlight look at the point of contact between the release fingers and face of the release bearing. If there is a visible difference in the position relative to the bearing face then it looks like a broken lining. If all fingers are the same then you need to have an assistant press the pedal whilst you observe the movement at each PTO plate adjuster screw. Check that movement of the rear plate (PTO pressure plate) is equal all round. The approximate gap at the screw heads should be 090". This figure is not critical but all must be the same. It may be necessary to reduce this figure on some tractors.
Have you slackened the locknut on each screw? You only need to slacken it enough to be able to turn the screw to gain the correct figure.
Carry out this adjustment and that should at least ensure that you have PTO disengagement.

I could not attach any photos this morning but I'm trying again.

Yeah the area has oil in it, quite a bit, I can see large drops of it up inside thru the inspection plate.

It'll have okay PTO power, for about 30mins of running, then it dies, sometimes completely.

Starting to think it's time to find a new tractor, this 73(or so) old one seems to be falling apart and not worth splitting it. (I have no way to do it myself, currently)

Thanks
